Fujiyama Electronics

Fujiyama Electronics, Inc. has been having difficulties with circuit boards purchased from an outside supplier. Unacceptable variability occurs between two drilled holes that are supposed to be 5 cm apart on the circuit boards. Thirty samples of 4 boards each were taken from shipments from the supplier as shown in the data from the worksheet Prob. 14-14, listed below.
a. Construct [pic] and R charts for these data.
b. If the supplier’s plant quality manager admitted that they were experiencing quality problems for shipments 18, 19, and 21, how would that affect your control chart? Show this adjustment on revised [pic] and R charts for these data.

The [pic] and R-charts, below, now show that the process is in control.

b) We can see from the above [pic]- chart that Samples 19 and 21 are out of control and from the R-chart, above, that sample 18 is out of control on its range. We must search for, and eliminate assignable causes and re-calculate the following control limits and related charts after dropping these 3 points:

The additional data shows that the process is still operating within control limits. See the "composite" control charts below.

Conclusions

• Using 30 samples, with the calculated control limits, the preliminary [pic] and R-charts showed that the process was out of control. • Assignable causes were investigated and three points were removed. Both the [pic] and R- charts were then in control. • The additional 10 samples show that the process is still operating within control limits. See the "composite" control charts above.

Recommendations

The report to management would include the analysis presented above. It should also include the recommendations that he/she:

• Monitor the process, to ensure that assignable causes mentioned above, don’t recur. If they are obviously due to non-recurring factors, the process should remain in control. If it is felt that control limits are still realistic, continue to monitor the process without changing them.

I. INTRODUCTION (4 min).

A. Opening Statement: How many people here smoke or use tobacco products? You really can’t take out a cigarette and smoke anywhere anymore. You can’t smoke in the bar anymore, and that was once a sacred ritual. You can’t go to your favorite coffee shop and enjoy a couple of cigarettes with your favorite brew. And when you are working and you want to have a smoke, you will have to go outside and smoke a cigarette, no matter the weather. It really has become a pain to be a smoker. Also, let’s not forget that it has become so expensive to smoke as well, with the price of cigarettes increasing every year it seems. Did you know there is a healthier alterative to smoking? And the fact of the matter is that this is not a new thing at all. It’s been around for a lot longer than you would think. Electronic Cigarettes are not only affordable but a lot healthier for you. But you can use them anywhere; there is no law that states you cannot use them in public places. Today I will discuss with you the history of the Electronic Cigarettes. After today’s class I’ll come back for a question and answer session about the topics we are about to discuss.

INSTRUMENTATION EQUIPMENT
2.0 INTRODUCTION
Instrumentation is the art of measuring the value of some plant parameter, pressure, flow, level or temperature to name a few and supplying a signal that is proportional to the measured parameter. The output signals are standard signal and can then be processed by other equipment to provide indication, alarms or automatic control. There are a number of standard signals; however, those most common in a CANDU plant are the 4-20 mA electronic signal and the 20-100 kPa pneumatic signal.
This section of the course is going to deal with the instrumentation equipment normal used to measure and provide signals. We will look at the measurement of five parameters: pressure, flow, level, temperature, and neutron flux.
2.1 PRESSURE MEASUREMENT
This module will examine the theory and operation of pressure detectors (bourdon tubes, diaphragms, bellows, forced balance and variable capacitance). It also covers the variables of an operating environment (pressure, temperature) and the possible modes of failure.
2.1.1 General Theory
Pressure is probably one of the most commonly measured variables in the power plant. It includes the measurement of steam pressure; feed water......

...EXISTING SYSTEM In Metropolitan cities, buses play an important role in the public transportation. Even though various kinds of transportations are implemented, the bus services still play a major part of the mass transit in Metropolitan cities. Due to increasing petrol and disel prices buses are the best alternative to own vehicles for the public. Additionally, it is much convenient since buses are available in atmost routes and bus passengers need not be worried for finding a parking area. The major problem faced by the passengers is delay in scheduled arrival time of bus to bus stop. The ITS- Intelligent Transport System is widely implemented to provide required information to passengers. In ITS every bus is mounted with a GPS module and electronic displays boards displaying arrival time of bus are placed in every bus stops. The Global position system (GPS) mounted as part of the Vehicle Mounted Unit in the bus will receive the longitude and latitude coordinates from the Satellite through a process of triangulation. This information is then sent across to the Central Control station through the wireless communication link – GSM / GPRS. The application at the Central control station on receiving the position inputs will update the display boards at the bus shelters / stops enroute and at the bus terminal platform display panel and the general display panel at the related bus terminals. The Passenger Information system will be driven by the following core sub-systems Central......

Fujiyama Electronics Case Study
This paper looks at constructing control charts from the data given for the variability in the circuits boards purchased from an supplier for the Fujiyama Electronics Company. Data of the thirty samples of four board each are fed into the analysis template to come up with the table below that gives an insight into the variability which would be further used to address the issue.
1. Calculate X-Bar-Bar, R-Bar, and associated control limits using the data in the table above.
From the above image, the X-Bar-Bar number can be seen in the top set of results titled “Center.” Therefore X-Bar-Bar = 5.1
The R-Bar result is the “Center” result the bottom set of data is R-Bar. Therefore R-Bar = 1.083
2. Create X-Bar•R (Average & Range) Control Charts from the data in the table above.
The X-Bar Control Chart is shown below
The R Control Chart is shown below
3. Discuss notable out-of-control conditions displayed in the completed X-Bar•R (Average & Range) Control Charts. Only consider points outside the control limits. Do not consider runs, set of points within certain zones, etc.
From the X-Bar control chart, we can see that two points #19 and #21 are above the upper control limit. From the R-Chart we can see that one point, #18 is above the upper control......

...To Use Electronics during School
Electronic devices, including cell phones, are very helpful resources during school hours. Emergencies always happen and in case of emergency cell phones come in handy. Students are required to pay attention in class, yet no one said anything about having to pay attention during lunch or passing periods. There should be no worries about students being distracted during lunch, or passing periods because class hasn`t started.
Electronic devices should be allowed during school hours. Parents always want to keep in touch with their children to see how they are doing during school. When there is an accident, there’s really no way to communicate with others because of this rule. Because of this rule, you don’t get any help because of the fact that you cannot use cell phones. Plus you don’t want to get in trouble, but you need to help the person who is hurt.
Phones can be silenced during class or study periods and active only in appropriate places. Like if you were after school and you have to silence it for athletic sports, stay after to get help from a teacher, in a library and etc. Because of a small mistake, students get punished. A teacher can assume that you’re texting because your phone went off, but they don’t have actual proof. Students need a stand for this because accidents always happen.
The other thing is that other electronic devices like cameras and IPods don’t make any disruptions unless they’re being used during school. Cameras......

Explain where an employee can reasonably except to have privacy in the workplace. Based on the fact that the United States doesn’t have a comprehensive law that protects privacy, there is almost no where in the work place that is private. Most laws give the employer the ability to monitor their employees as long as they have a valid reason for their monitoring. With the advance tin technology employer’s ability to monitor their employees has expanded over last 20 years.
Employers have the right to monitor telephone calls, computer usage, electronic mail, voice mail, and video monitoring. Most......

Computers
Computers are used to send e-mails across to other people via the internet and most commonly mobile phones. Another way in which computers are used at Oldbury Academy is via the gateway. This is almost comparable to a portal between teachers and students. It allows for pupils to access work in the case of a teacher being absent, teachers may also display messages about extra curriculums on the gateway and any other relevant information. Oldbury Academy also uses a system called SIMS (School Information Management System) which allows teachers to track the whereabouts of any given student via giving them a present mark and electronically noting down their timetabled lessons.
Here is an example of Student Announcements which are placed onto the gateway by teachers, to communicate information to students.

E-mail
Oldbury Academy uses e-mails to send messages across to staff in regards to information such as assemblies or student’s absences. Teachers may also use e-mails to inform pupils of any homework, and students may e-mail back teachers for help and guidance. Oldbury Academy may also e-mail parents who have opted for this and send them things such as the School Newsletter, or any other important information a parent may need to know about their child’s education.

* Even though a staff member might have access to a patients prescription medication list, or other medical information, it is still unethical for that information to be read, or accessed unless it pertains that that employee’s job. This is why there should be limited access on who can access certain data.
* Employees need to be advised of proper internet use, which should only be job related issues. Internet browsing might be thought of as innocent and not malicious, but the anti-virus protection that is installed on the computer can only protect so much. It is only designed to scan for certain definitions it is programmed with. With the rate of new virus’s being created each day, a safe practice needs to be implemented when searching on the internet.

Professor; Earl Wiese
Fujiyama Electronics, Inc. has had difficulties with circuit boards purchased from an outside supplier. Unacceptable variability occurs between two drilled holes that are supposed to be 5 cm apart on the circuit boards. Thirty samples of 4 boards each were taken from shipments from the supplier.
With the information input and calculated we find that center X-bar number is 5.1 and the R-bar number is 1.803 with a Range of .68.
When reviewing the X-chart we find that sample number 18 and 20 are outside the upper range and sample 18 is also outside the upper limits of the R-chart.
Upon review we find that sample number 18 are assignable conditions which can be removed and produces the following results.
What we find with this additional information is that the new X-bar becomes 5.105 an increase which is also an increase in the UCL and the LCL and reduces the area of the control limits, but caused no movement in the range. However sample number 18 and 20 are still outside the upper limit on the X-chart but all sample numbers fall within the control limits in the R-chart.
If we remove both sample 18 and 20 from the original data set of 30 the following information is produced.
Again we have a reduction in the X-bar control limits and sample 18 and 20 still remain outside the upper limits but fall within the limits of the R-chart....
